Hi,
I am trying to use normal maps with a Light 2D, and it is working in design time… but it automatically gets disabled on runtime. I even tried to set it on during runtime, but the property is readonly and can’t be set from a script. Please help!
Aaaaahm… I dunno if it is about a bug or not, but I found something at:
C:\Program Files\Unity\Hub\Editor\2021.1.3f1\Editor\Data\Resources\PackageManager\BuiltInPackages\com.unity.render-pipelines.universal\Runtime\2D\Light2D.cs
There’s a boolean serialized field that is set to false:
[SerializeField] bool m_UseNormalMap = false; // This is now deprecated. Keep it here for backwards compatibility.
And then, in Awake() we have this:
if (!m_UseNormalMap && m_NormalMapQuality != NormalMapQuality.Disabled)
m_NormalMapQuality = NormalMapQuality.Disabled;
So we have that NormalMapQuality is always set to Disabled. As I said, I dunno if it is a bug, but I found no solution anywhere, no answers in forums and I needed this working, so I changed the initial value from false to true in the Light2D.cs file (I had to grant write permissions to do it), I started my project and I replaced all my spot 2d lights with new instances. Result: working.
